ROAD-GRADR.

SPECIFICATION forming part of Letters Batent N o. 561,264, dated .Tune2,1896. Application filed December 28,1895. Serial No. 573,634. (Nomodel.)

To all whom it may concern,.-

Be it known that I, JASON W. MACY, acitizen of the United States,residing at Searsborough, in the county of Poweshiek and State of Iowa,have invented certain new and useful Improvements in Road-Graders; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others Vskilled in theart to which it appertains to make and use the same.

This invention relates to certain new and useful improvements inroad-scrapers; and it has for its objects, among others, to provide asimple, cheap, and light road grader or scraper that can be capable ofaccomplishing more work in a given time than the old forms and that withmuch less exertion and wear on the horsesor wear upon the scraper. Iprovide a light scraper mounted on a frame and provided with rollershaving means for adjustment so as to change their position to suit thecharacter of the work to be done. The bearings for the axles of theserollers are extended to forni handles.

The device as a whole is simple, composed of few parts and those readilyassembled, and not liable to get out of order or to be injured in use.

Other objects and advantages of the inven tion will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention in this instance resides in the peculiar combinations andthe construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, 'and thenparticularly7 pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form apart of thisspecication, and in which- Figure 1 is a perspective view of my improvedroad-grader. Fig. 2 is a vertical longitudinal section through the same.Fig. 3 is a vertical crosssection through the aXlesof the rear rollers.Fig. 4. is a detail showing the construction of the handles.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates theshovel or scraper, which may be of any suitable size and capacity, thesides being tapered and diverging, as shown, and the point slightlyturned up, as seen at a. To the sides near their front end are securedthe arms or braces B, the forward ends of which are secured to the poleor tongue O in any well-known or suitable manner. The ends are firstpassed through suitable hangers or guide-loops D, depending from theunder side of the transverse bar E, to which the rear end of the tongueis secured in any desirable way. The braces or arms may be curved moreor less, as may be found most desirable. This forms -a very strong andlight machine.

Secured to the under side of the scraper near the rear end thereof arethe flanged plates or brackets F, in the vertical portions of which arejournaled the transverse shafts G, carrying the rollers H. There arepreferably two sets of these rollers, being, of course, of differentdiameters, those at the rear being larger than those at the front. Theinnermost of these plates or brackets are extended rearward, as shown,and are bent or folded uponv themselves to form the handles I, by whichthe scraper may be tilted more or less to make it cut deeper or not sodeep, as may be required. These handles serve also for other purposes,such as an aid in dumping the scraper when desired.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages.

l. The combination with the scraper, of the anged plates secured to theunder side thereof and one of each pair extended to form a handle, asset forth.

2. The road-grader described, consisting of the scraper, the brace-armssecured thereto, the cross-bar having hangers through which saidbrace-arms extend, the tongue secured to said brace-arms, the flangedbrackets on the under side of the scraper and extended to form integralhandles, and the rollers of different diameters carried by shaftsjournaledin said brackets, substantially as specified.

V In testimony whereof I have signed this specification in the presenceof two subscribi ing witnesses.
